Abstract

In this study; prealloyed NiTi powders and ball mills with 2%, 4%, 6%, 8% and 10% Zn powder ratios were subjected to mechanical milling for 60 minutes. The milled NiTi + Zn powder mixtures were pressed under 750 MPa pressurize and then sintered at 1000 degrees C for 60 minutes. In order to determine the microstructural changes in the samples which were milled, pressed and then sintered samples; SEM, EDS, DSC and XRD analyses were applied, respectively. Changes in powder morphology were observed, depending of the increasing Zn content in the NiTi + Zn powder mixtures and it was determined that the powders containing 10% Zn completely covered the surface of the NiTi powders in a homogeneous manner after milling.
